Ensure you have run eval $(op signin) in your current terminal session so Ansible can fetch the password.

On a Proxmox host or container, you can force a DHCP renewal with:

On the Proxmox host itself (Debian-based):

# Release and renew
dhclient -r <interface>
dhclient <interface>

Or if using systemd-networkd:

networkctl renew <interface>

Inside an LXC container:

Same commands apply depending on what’s managing networking inside the container. If it’s a Debian/Ubuntu container:

dhclient -r eth0
dhclient eth0

Or restart the networking service entirely:

systemctl restart networking

For a VM (QEMU/KVM):

You’d need to do it from inside the guest OS — Proxmox doesn’t control the guest’s DHCP client directly.

If you changed the DHCP reservation on your UniFi side and want the device to pick up the new IP, the fastest approach is:

1. Release the old lease: dhclient -r <interface>
2. Optionally clear any cached lease file: rm /var/lib/dhcp/dhclient.<interface>.leases
3. Request a new lease: dhclient <interface>

Since you’re running UniFi, you can also delete the old lease/fixed IP mapping from the UniFi controller to make sure the server hands out the correct address on the next request.
